Features Jackpot Train by Red Tiger Gaming is a slot built around Train symbols, a Wheel scatter on reel 3, and a series of bonus features. In the demo version, players can play for free and practice before playing for real money while exploring the game’s spin-based mechanics and symbol upgrades.
The main bonus round is triggered by collecting Train symbols, which unlock Free Spins, Silver Spins, Golden Spins, or Diamond Spins depending on how many appear. During these rounds, Train symbols leave marks that can be upgraded from Coin to Silver Bar, Golden Bar, Diamond, Triple Diamond, and Pile of Diamonds, with prizes awarded at the end of the feature. The Wild symbol appears on reels 2, 3, and 4 and substitutes for paying symbols.
The Wheel scatter may activate a Wheel bonus with Instant Prize wins, extra Free Spins, bonus multipliers, or an Upgrade that leads to the Major Wheel. Feature Buy options are also listed, including access to the Wheel and different spin levels, with prices set as multiples of the stake.
